The Delhi Police today told a court here that the suicide notes of former air hostess Geetika Sharma and her mother should be considered as concrete evidence against former Haryana minister Gopal Kanda and his aide Aruna Chaddha accused of abetting her suicide.

In its arguments on framing of charges before District Judge S K Sarvaria, the prosecution said suicide notes written by Geetika are the strongest piece of evidence against the accused.

Additional Public Prosecutor Rajiv Mohan also said the suicide notes written by Geetika's mother, who committed suicide on February 15, also point towards culpability of Kanda and Chaddha.

The submissions were opposed by Kanda's counsel.

The court has fixed April 2 for hearing further arguments.

Both Kanda and Chaddha are accused of abetting Geetika's suicide. She was found dead at her Ashok Vihar residence in Delhi on August 5, last year.

In her suicide note, Geetika had said that she was ending her life due to "harassment" by Kanda and Chaddha.

Geetika's mother Anuradha Sharma also committed suicide and had left behind two notes in which she blamed the duo for driving her daughter to take such an extreme step.

In its main and supplementary charge sheets, Delhi Police has said Kanda was obsessed with Geetika and wanted to bring her back in his company to sexually exploit her.

Kanda and Chaddha have been charge-sheeted for abetment of suicide, criminal conspiracy, criminal intimidation, forgery of valuable security, forgery with intention to cheat and harm reputation, using forged documents as genuine and destruction of evidence under the IPC.

They have also been booked under Section 66 of the Information Technology Act which deals with computer hacking.
